Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

3.8.1 Removing experts

Course subject(s) Module 3. Performance-based weights and the Decision Maker

Recall the previous example about the correlation between intelligence in primary school children and other personality traits and success in several aspects of life. The experts assessments are provided below.

Question Realization Expert A

5% 50% 95%

Expert B

5% 50% 95%

Expert C

5% 50% 95%

1 24 2 5 7 20 23 34 20 25 28
2 11 12 13 15 8 10 11 10 13 15
3 68 87 89 92 60 70 90 65 67 70
4 47 2  5  8 20 35 45 42 44 46
5 31 48  50  52 30 35 40 32 33 35

As mentioned in the hint of the previous question, the intrinsic range of Question 1 is [0,37.2].

Consider now removing Expert 1 from the pool with experts. We are left with Expert 2 and Expert 3 assessments.

We see how the intrinsic range of Question 1 has changed when Expert 1 assessments have been removed!

Consequently, the information score of Expert 2 and Expert 3 for Question 1 will change when Expert 1 is removed!!

This is because the intrinsic range, through it’s values L* and U* is part of the formula that compute the information score.
